The future of Obamacare has been in limbo for the better part of seven years now. Ever since its partisan-line passage in 2010, Republicans have vowed to repeal President Obama's signature legislation. In fact, Republicans have voted to repeal or change Obamacare no less than 54 times to date. Those efforts had little hope of success while Obama held a presidential veto. But with President Trump now in the Oval Office, congressional Republicans are confident that their move to repeal Obamacare, beginning with a House vote on Thursday, will ultimately be enacted. In stringent opposition this legislative change, however, are the thousands of Twitter users who have employed the hashtag #ObamacareHelpedMe to show the benefits of the ACA. UPDATE: The AHCA has officially passed the House with a majority of votes, 217 to 213.

According to analyses from both the Congressional Budget Office (CBO) and a new Harvard study based on "RomneyCare" in Massachusetts, Republicans' repeal and replace plan could have catastrophic consequences. Their findings predicts millions will lose their insurance, and the new market will be far less solvent. Increases in price will cause lower-income buyers to drop out of the market, which drives up emergency room visits — and those are both costly and less effective than preventative health care. Additionally, those who most need health care — the elderly and sick — will be a disproportionately large portion of buyers. Cue financial breakdown.

Twitter is having none of that. Here are just a sampling of what users had to say about how Obamacare helped them:

Cardiologist For Son With Heart Defect

#ObamacareHelpedMe afford Cardiologist visits for my son, born with a Congenital Heart Defect. AHCA may ensure he DOESN'T get coverage.

After Jimmy Kimmel's emotional story about his own infant son's need for heart surgery, the television host implored people to think about what those without health insurance would do in his shoes. Here's another example of how Obamacare helped a family get vital help for their son.

Brain Surgery

@RVAwonk Obamacare paid for my brain surgery. I lost corporate insurance when my husband died a few weeks before surgery. #ObamacareHelpedMe

Thriving With A Hereditary Disease

Hereditary Angioedema is a hereditary condition, aka pre-existing condition. Obamacare made it illegal to bar people from buying insurers for that reason. And that made a world of difference for this woman.

Prenatal and maternity coverage.

Republicans have said some outrageous things about health care, but some of the most absurd and offensive surround how they shouldn't have to pay for women's problems — problems like pregnancy, and I'm not joking here. Obamacare mandated maternity care. Ask any mom how much that means, if you're unsure.

C-Sections Are Not A Pre-Existing Condition

Cut my payments in half. Was finally able to afford a child. Now C-section will be pre-existing condition... #ObamacareHelpedMe

Mental Health Coverage Saves Lives

The stigma surrounding mental illness is finally receding, at least a little bit, and many who needed mental health care were finally able to afford it with Obamacare. The Republican plan cuts Medicaid so drastically that countless people who need mental health care will be left without any options. "Many will instead end up homeless, in jail or dead," Linda Rosenberg, CEO of the National Council for Behavioral Health, told USA Today.

After recovering from a massive health crisis like cancer, no one should have to spend the rest of their life worrying about basic health coverage.

The truth about the health insurance market prior to Obamacare is that it punished potential buyers for all manner of "pre-existing conditions." As evidenced above, many of those encompass conditions that people are born with, or they "acquire" in the process of giving birth (like a C-section). Other categories include horrific illnesses like cancer.

It's almost impossible to imagine a world in which mothers who needed a C-section see themselves forever consigned to higher premiums, to say nothing of cancer survivors unable to get basic health insurance.

House Minority Leader Nancy Pelosi dubbed the Republican bill a "moral monstrosity," one she predicts will lead to devastating losses for the party at the ballot box. It's hard to argue with that assessment.
